Reviewing the general advice from all quarters the size of frame fixings is not always consistent.
I have 8 *120 and 10 * 100 'in stock'.
Trivial, I know, but although I haver started by using the 8 * 120 I note that others have used 10 * 100.
Just generally worrying if the 8 * 120 are man enough for the job. They certainly seem preety strong although the heads are a little fragile.
